摘要
本文对三台县建筑物室内天然本底辐射水平进行了调查,其结果:为(10.97±1.98)×10^(-8)GY·h^(-1),室内天然本底辐射剂量因建筑材料不同而差别有高度显著性(P<0.01),主体建筑和地雨材料相同,其γ辐射剂量率不同楼层存在差别亦有高度显著性(P<0.01);居民个人年有效剂量当量0.54mSV,集体年有效剂量当量为7.39×10~2人·SV。
This article decls with our investigation on natural radiation background level of indoor environment of Buildings in Santai county.The result is (10.97±1.98)×10^(-8)GY·h^(-1).The dose rate of natural radiation background levels differ a lot in their building materials and they show a high significance (P<0.01). Even if the same materials for the main building and floors were used, the dose rate of γ radiation level changes with different floors. They still show high significance(P<0.01) . The annual effective equalent dose of each resident is 0.54 m S V. While the total annual effective equalent dose of the whole county is 7.39×10~2 P.SV.
